preying mantis 

The only insect that makes a great pet.

They hatch on Memorial Day, give or take a few days. About July 4 they are large enough to find in the wild. If you have an egg case in a terrarium, you'll be able to see them as soon as they hatch, but good luck finding these little guys outside.

They all have wings, but only adult males fly. Males are slightly shorter, a lot skinnier, and much more hyper. They are a lot harder to catch and somewhat more difficult to tame.

If well fed, they are much less cannibalistic than commonly thought. Yes, a small percent are Jeffrey or Jennifer Dahmers, but most are not.

Unfortunately they are short lived. In the wild they die between fall and winter. In captivity they still might die in fall, but some will make it almost to next spring.

It may seem cruel, but it's usually best to clip their wings in the fall, as they get a disease which starts out as brown spots on their wings but soon turns into holes. They die sooner if you let them get this, or let it progress. Cut the wings and put some Neosporin CREAM on them with a Q-tip.

FOOD: Katydids are their favorite. Small grasshoppers are good. Moths are excellent. You may have to buy crickets in the winter. Baby mantids eat flightless fruitflies (PETSMART).
Preying Mantis Kung Fu mimicks the fighting style of the Preying Mantis.

Preying Mantis 

Describes the physical position of someone who is gurned up to their tits.

Put your arms straight out in front of yourself, then bend your elbows so that your foreams are at a right angle to your upper arms, and parrallel to your body. Fully extend your fingers, then bend your wrists down, to form a sort of 'M' shape with your forearms and hands.

When accompanied by rolling eyes, a swinging underbitten jaw, and low-soft groaning noises, can be highly amusing.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
